Video System

1. The description the requirement of the video system is as below. -------------------------------------------------A video store system runs a series of fairly standard video stores. Before a video can be put on the shelf, it must be cataloged and entered into the video database. Every customer must have a valid customer card in order to rent a video. A customer rents the video for three days at a time. Every time a customer rents a video, the system must ensure that they do not have any overdue videos. If so, the overdue videos must be returned and an overdue fee must be paid before the customer can rent more videos. Likewise, if the customer has returned overdue videos, but has not paid the overdue fee, the fee must be paid before a new video can be rented. Every morning, the store manager prints a report that lists overdue videos. If a video is two or more days overdue, the manager calls the customer to remind him/her to return the video. If a video is returned in a damaged condition, the manager removes it from the video database and may sometimes charge the customer. a. Draw a use case model for the video system described above. Manager

Essay on Robert Scholes’s On Reading a Video Text
“The American Dream”, the myth America has built upon itself. What are the first images that pop in our minds when we hear this phrase? The big house? The perfect job? Living in a land of equal opportunities? That hard work will inevitably be rewarded with the deserved economical goods? The immigrant working for a better life? These are all heart-warming images that have been implanted into our conscious since we were little. “Implanted” seems like a harsh word though, it by definition is the action of inserting something into someone’s body. Kind of like a predetermined seed of ideas being burrowed deep into our minds. How can something as beloved as “The American Dream” be seen as an intruder to our conscious? Shouldn’t it be welcomed? “The American Dream” essentially promotes hard work and well-being doesn’t it? Unfortunately, everything is bound to have a malicious side to it. “The American Dream” has been victimized by marketers in order to sell products and use it as a tool to take advantage of “the seed” implanted upon us.

...ESRB states that the "ratings are designed to provide information about video and computer game content, so you can make informed purchase decisions." The ratings consist two parts one is the ratings symbol which can be found on the front of the box. One the back of the box the ESRB also includes a description of the game so the purchaser knows why a game is rated the way it is.

...Has America Seen Enough? A Stronger Rating System is a Must
Many of today's youth are easily influenced by their environment. Their environment can include their family, friends, school, and even media (television, music, video games). With technology rapidly advancing, video games are having an even greater impact on youth. In the last few years, there has been a steady increase in the amount of violence contained in all media, especially video games. According to Alison Motluk, "more than 90 per cent of American children play video games every day, and half of the top sellers contain extreme violence" (10). Playing these violent video games is having a direct effect on aggression levels as seen in the recent rise of school violence. Many times the individuals involved have stated that they got their ideas from playing violent video games. Obviously, with youth violence on the rise, changes need to be made in order to help control this situation. A stricter rating system needs to be applied to video games, and more importantly the new rating system should be heavily enforced wherever video games are sold so that maturity levels are met before being allowed to purchase a video game.
Computer and video games have been rated using a rating scale since 1994. Video...

Videoconferencing is the conduct of a videoconference (also known as a video conference or videoteleconference) by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions.

The process or ways by which video conferencing take place that is called video conferencing system.
Videoconferencing differs from videophone calls in that it's designed to serve a conference or multiple locations rather than individuals. It is an intermediate form of videotelephony, first used commercially in Germany during the late-1930s and later in the United States during the early 1970s as part of AT&T's development of Picturephone technology.
With the introduction of relatively low cost, high capacity broadband telecommunication services in the late 1990s, coupled with powerful computing processors and video compression techniques, videoconferencing has made significant inroads in business, education, medicine and media. Like all long distance communications technologies (such as phone and Internet), by reducing the need to travel to bring people together the technology also contributes to reductions in carbon emissions, thereby helping to reduce...

2. Describe Barco’s product line evolution over time – focus on the time when
different products in the line were introduced and upgraded.
Barco entered the projection systems market in 1981 with the development of a video projector for showing motion pictures in airplanes. Its first projector, named the BarcoVision1 (BV1) was well-received and sold strongly in the U.S and European markets. After this success, Barco’s board of directors met to evaluate the company’s three potential directions: (1) It could downgrade its technology to suit consumer video applications (2) it could upgrade its technology for long-distance, high-performance video projection or (3) it could enter the untested market for computer applications. Seeing significant potential expansion in the projection market for computer applications, Barco made the decision to grow its projection division. In 1983, BPS introduced the BarcoData 1(BD1), the first computer...
